Increase Logo Size

Does anyone know how can I increase the size of my logo without it overlapping everything else in the header. See pic. Thanx!

Yes you can do it in the main.css file.
look at the section called main : look for

.topBlock
 {
  position:relative;
  height:150px;   (this is mine setting)
  border:0px dashed blue;
  margin-bottom:0px;

Thank you sir!

hello,

In the theme you use go to /css/general.css  or /base/css/general.css
